Abstract
A drill pipe has a tubular body with a first end, a second end, an outer wall and an inner wall. A first connection end is connected to the first end of the tubular body and a second connection end is connected with the second end of the tubular body. The first connection end and the second connection end have an inner wall and an outer wall, the outer wall is substantially cylindrical in shape and the inner wall defines a central cavity. The first connection end and the second connection end are sized to allow for mating with a corresponding drill pipe. The outer wall of the tubular body is substantially cylindrical in shape. The inner wall of the tubular body defines a central cavity that is in fluid communication with the central cavity of the first connection end and the second connection end. The inner wall has at least one land and at least one groove. The at least one groove has at least one twist along the length of the tubular body.
